Criteria

Inclusion Criteria

  • Subjects will be females and/or males, non-smokers, 18 years of age and older.
  • Female Subjects will be post-menopausal or surgically sterilized.
  • Post-menopausal status is defined as absence of menses for the past 12 months,
  • Sterile status is defined as hysterectomy, bilateral oophorectomy or tubal ligation at least 6 months ago.

Exclusion Criteria

Subjects to whom any of the following applies will be excluded from the study:

  • Clinically significant illnesses within 4 weeks of the administration of study medication.
  • Clinically significant surgery within 4 weeks prior to the administration of the study medication.
  • Any clinically significant abnormality found during medical screening.
  • Subjects with a history of renal, hepatic or cardiovascular disease, tuberculosis, epilepsy, asthma, diabetes, psychosis or glaucoma will not be eligible for this study.
  • Any reason which, in the opinion of the medical subinvestigator, would prevent the subject from participating in the study.
  • Abnormal laboratory tests judged clinically significant.
  • Positive urine drug screen at screening.
  • Positive testing for hepatitis B, hepatitis C or HIV at screening.
  • ECG abnormalities (clinically significant) or vital sign abnormalities (systolic blood pressure lower than 90 or over 140 mmHg, or diastolic blood pressure lower than 50 or over 90; or heart rate less than 50 bpm) at screening.
  • Subjects with BMI ≥30.0.
  • History of significant alcohol abuse within six months of the screening visit or any indication of the regular use of more than two units of alcohol per day (1 Unit = 150 mL of wine or 360 mL of beer or 45 mL of alcohol 40%).
  • History of drug abuse or use of illegal drugs: use of soft drugs (such as marijuana) within 3 months of the screening visit or hard drugs (such as cocaine, phencyclidine (PCP) and crack) within 1 year of the screening visit.
  • Any food allergy, intolerance, restriction or special diet that, in the opinion of the medical subinvestigator, contraindicates the subject's participation in this study.
  • History of allergic reactions to lamotrigine.
  • Use of any drugs known to induce or inhibit hepatic drug metabolism (examples of inducers: barbiturates, carbamazepine, phenytoin, glucocorticoids, rifampin/rifabutin; examples of inhibitors: antidepressants, cimetidine, diltiazem, erythromycin, ketoconazole, MAO inhibitors, neuroleptics, verapamil, quinidine, valproic acid, use of an investigational drug or participation on an investigation study within 30 days prior to the administration of the study medication.
  • Use of prescription medication within 14 days prior to administration of study medication or over-the-counter products )including natural products, vitamins, garlic as a supplement) within 7 days prior to administration of study medication, except for topical products without systemic absorption.
  • Subjects who have had a depot injection or an implant of any drug 3 months prior to administration of study medication.
  • Donation of plasma (500 mL) within 7 days. Donation or loss of whole blood prior to administration of the study medication as follows:
  • Less than 300 mL of whole blood within 30 days or
  • 300 mL to 500 mL of whole blood within 45 days or
